Forces
Learn what forces are and what they can do. Forces View Details Mass, Weight & Gravity Learn that the weight of an object on Earth is the result of the gravitational attraction between its mass and that of the Earth, and know that weight is a force so is measured in newtons. Mass, Weight & Gravity View Details Unbalanced Forces Learn that unbalanced forces change the speed or direction of movement of objects and that balanced forces produce no change in the movement of an object. Unbalanced Forces View Details Balanced Forces Learn that balanced forces produce no change in the movement of an object. Balanced Forces View Details Stretching Materials Learn that extension is proportional to load, within the elastic limit of a material. Stretching Materials View Details Friction Find out how frictional forces, including air resistance, can affect the motion of an object. Friction View Details Useful Friction Learn how frictional forces can be useful. Useful Friction View Details What Forces Do Learn what forces can do and how to measure them. What Forces Do View Details Pivots and Levers Learn that forces can cause objects to turn about a pivot and that the turning effect of a lever depends on the force and its distance from the pivot. Pivots and Levers View Details Calculating Moments Understand the principle of moments and its application to situations involving one pivot. Calculating Moments Forces and Motion Clockwise and Anti-clockwise Moments Learn that a moment is a turning force, which can be clockwise or anti-clockwise. Clockwise and Anti-clockwise Moments View Details Forces 1
Description:To know that gravity is a force of attraction which acts on Earth towards the centre of the planet and to know the size of the force of gravity depends on the mass of each object and the distance between them. Launch:Forces 1 Forces 2
Description:To understand the concept of work and how to calculate it; the centre of gravity and the theory of equilibrium. Launch:Forces 2 |
